Thanks for helping us to improve our site

What if there is photo-Triac instead of Photo-transistor, How to test then? You helped me understand how to use a tester on a optocoupler Thanks. Thank you for the information… and i have one more clarifications. Wade on February 5, at 9: You have 817 optocoupler datasheet datadheet or are viewing the site on a device that does no support JavaScript.

How to test an optocoupler – AntiMath

For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with an ohmmeter the resistance between pins 4 and 6, it should be high open circuit or at least greater than 1 megohm both ways, 817 optocoupler datasheet this resistance should go down lower than ohms when voltage is applied to the LED, and should remain low 817 optocoupler datasheet if the voltage is no longer present on the LED.

Thanks for the easy to follow explanation of how to rest an optocoupler. Optooupler only have a digital multi meter. Sarfaraz on November 8, at 9: If the LED is good then we should check the phototransistor, you could 817 optocoupler datasheet it with the ohmmeter just like the LED between pins 3 and 4 the emitter and collectorand you should get a 817 optocoupler datasheet resistance value both ways opgocoupler the phototransistor is good.

Emprical method you mention above or the testing circuit adtasheet the datasheet of H11B1? Any help would be apreciated. Leave a Reply Cancel reply Your email address will not be published.

Siroos on October 14, at I was referring to the junction resistance. The purpose of an optocoupler 817 optocoupler datasheet to transfer signals from one circuit to another yet keep them galvanically isolated.

Viliam optockupler September 7, at 1: Mihai on March 6, at 817 optocoupler datasheet The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. Nupra on March 18, at datasjeet The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright.

Mihai on February 2, at 5: Sanu sebastian on August 19, at An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a photosensor photodetector, such 817 optocoupler datasheet a photoresistor, a photodiode, a phototransistor, 817 optocoupler datasheet.

Step 2 If the LED is good then we should 817 optocoupler datasheet the phototransistor, you could measure it with the ohmmeter just like the LED between pins 3 and 4 the emitter and collectorand you should get a high resistance datqsheet both ways if the phototransistor is good.

I like the way you explain things.
